The goal for this session is to give a guided handson tour of Math Forum features of special interest to teachers.
Note: We suggest that you bookmark this page so that you can easily get back to it as "home base" if you wander away from the tour.
The Math Forum  http://mathforum.org/
The Math Forum is an online community of teachers, students, researchers, parents, educators, and citizens at all levels who have an interest in mathematics and math education. The Math Forum has consistently been recognized as the leader in its field by continuing to provide highquality content and useful features. This recognition is reflected in traffic to the site; in an average month, about 80,000 unique visitors make about 200,000 visits, each lasting about 9 minutes and resulting in over 4 million pageviews.
The home page offers easy access to all of the Math Forum services, with specific entry points provided to aid navigation for the novice, such as the Student Center and Teachers' Place. There are also links to 'What's New' on the site, a Search for Math on the Internet, and more.
Problems of the Week  http://mathforum.org/pow/
The Problems of the Week are designed to challenge students with nonroutine problems, and to encourage them to explain their solutions. There are six Problems of the Week (PoWs): Elementary, Middle School, Algebra, Geometry, Trigonometry & Calculus, and Discrete Mathematics. Each PoW is a mentored environment  i.e., every student submission is responded to by a mentor, and students are encouraged to revise or strengthen their solutions.
There is a searchable archive of over 700 problems, each with the administrator's comments and highlighted solutions. Current or archived problems can be integrated into courses in a variety of ways: as introductory or summary activities, as enrichment, to encourage teamwork or written communications, to allow the teacher unique access to student thinking, to allow students to mentor other students, and more. See the powteach discussion for more ideas.
 by using the "Print This Problem" link just above the title, any current or past problem can be printed with a simple "Math Forum Problem of the Week" header; this allows problems to be used without an indication of a course or grade level;
 teachers can request accounts that can be sorted by class or alphabet, and that track each student's last posting date and the number of correct, bonus and total submissions; to apply, follow the "Teacher Account" link for a particular PoW from the Teacher Information page; here is a sample account page;
 teachers are invited to read through and contribute to a powteach discussion, which has been established to facilitate conversation about general issues concerning the instructional use of the Problems of the Week, as well as ideas related to specific problems.
Ask Dr. Math  http://mathforum.org/dr.math/
Take a moment to think of and record a question your students might ask about something in mathematics, or a mathematical question that has come up in your own explorations.**
Ask Dr. Math is an askanexpert service in which anyone in the world can pose a math question at any level. A cadre of volunteer 'doctors' selects and responds to problems of interest. In addition to an archive of over 5,000 questions and answers that is searchable by level and topic, there are:
 a set of nearly 50 Frequently Asked Questions on the Dr. Math FAQ page, including items about multiplying a negative by a negative, permutations and combinations, the Fibonacci sequence, Pascal's Triangle, and more;
 a Classic Problems page, including such favorites as: "two trains leave from different cities ..."; "if one child in a twochild family is a boy, what is the likelihood that the other child is a girl?"; "how large must a group be so that the chance of at least two people having the same birthday is ..."; etc.;
 a Formulas page, which shows formulas for area, perimeter, and volume of a variety of figures, the connections between coordinate systems, and more.
**On our Guidelines page, you will find ideas about the classroom use of Ask Dr. Math, such as the introductory activity at the beginning of this section.
Teacher2Teacher  http://mathforum.org/t2t/
Like a virtual teacher's lounge, Teacher2Teacher is an environment in which questions are asked and opinions are shared about topics across the broad spectrum of interest to teachers, including classroom techniques, activities, resources, professional development, etc. The archive contains over 500 questions and their related discussion threads. Initial responses are provided by master teachers, including Presidential Awardees for Excellence in Mathematics Teaching, and many questions stimulate a host of responses as issues are explored and opinions expressed.
A frequently asked question like "what role can manipulatives play in teaching mathematics?" can generate much discussion, as can be seen on this FAQ page.
Internet Mathematics Library  http://mathforum.org/library/
The Math Forum continues to collect, organize, catalog, and annotate thousands of mathrelated Web sites from diverse sources to create its Internet Mathematics Library. You can search or browse through over 7,500 items in the collection, organized under the headings of Mathematics Topics, Resource Types, Mathematics Education Topics, and Educational Level. "Drilling down" from any heading takes you to a set of categories, then to a page showing subcategories, selected sites, and all sites in the category.
Math Forum Searches  http://mathforum.org/grepform.html
We have over 300,000 pages of content, so this is quite an extensive search field. Given that ours is a fulltext searcher, you may want to focus a search in a specific area, or use the "that exact phase" and "complete words only" options.
Efficient searching is an art. You may find our Searching Tips and Tricks page helpful, and our Search Features page offers even more detail about such items as the "Starting Points" that are generated for many keywords and topics, and the automatic spell correction, which is often helpful. These features are the result of human efforts to make the search environment more userfriendly. We invite you to contact the Webmaster (webmaster@mathforum.org) to clarify any unresolved confusion or questions.
Web Units and Lessons  http://mathforum.org/web.units.html
The Math Forum is committed to building on the activity of the teachers,
students, and researchers who use it. The Forum provides a platform and the
opportunity to share excellent resources and materials, such as Suzanne Alejandre's Mathematics Lessons.
Exemplary materials created by people in the extended Math Forum community
are highlighted in the changing gallery of the Forum Showcase.
Math Forum Internet Newsletter  http://mathforum.org/electronic.newsletter/
Our electronic newsletter is sent out via email once a week to those who subscribe, and is archived on our site. It offers tips about what we have at the Math Forum and how to find it, notes about new items on the site or on the Internet, questions and answers from services like Ask Dr. Math or the Problems of the Week, suggestions for K12 teachers and students, and pointers to key issues in mathematics and math education.
Discussion Groups & Projects  http://mathforum.org/discussions/
The Math Forum's discussion archives include many mathematics and matheducationrelated newsgroups, mailing lists, and Webbased discussions, such as the powteach discussion mentioned above, as well as mathteach, numeracy, geometryprecollege, k12.ed.math, etc. Many discussion sites are very active, like sci.math, which had about 900 threads posted in September 2000 alone.
Join Us As a Contributor  http://mathforum.org/join.forum.html/
There are many ways to contribute to the Math Forum community. Beyond using the various services we provide, many people subscribe to the newsletter, participate in T2T and other discussions, and make suggestions, such as alerting us to other good materials and websites they have discovered. Others find satisfaction in sharing their content as Web units or lessons, or showcasing their students' work. Many people voluteer their time and efforts to respond to T2T or Ask Dr. Math questions, while others act as mentors for one of the Problems of the Week.
In whatever ways this might work best for you, please know that you are always welcome and invited to interact with us in our online math ed community center.
